Hera makes Python code easy to orchestrate on Argo Workflows through native Python integrations. It lets you construct and submit your Workflows entirely in Python. ⭐️ Remember to star!

# Hera
| <img src="https://raw.githubusercontent.com/argoproj-labs/hera/main/docs/assets/hera-logo.svg" alt="Hera mascot"> | Hera is the go-to Python SDK to make Argo Workflows simple and intuitive. Easily turn Python functions into containerised templates that run on Kubernetes, with full access to its capabilities. |
|---|---|
[See the Quick Start guide](https://hera.readthedocs.io/en/stable/walk-through/quick-start/) to start using Hera to
orchestrate your Argo Workflows!
```text
The Argo was constructed by the shipwright Argus,
and its crew were specially protected by the goddess Hera.

## Hera at a glance
```python
from hera.workflows import DAG, Workflow, script
# Turn a function into a reusable "Script template"
# using the script decorator
@script()
def echo(message: str):
print(message)
# Orchestration logic lives *outside* of business logic
with Workflow(
generate_name="dag-diamond-",
entrypoint="diamond",
) as w:
with DAG(name="diamond"):
A = echo(name="A", arguments={"message": "A"})
B = echo(name="B", arguments={"message": "B"})
C = echo(name="C", arguments={"message": "C"})
D = echo(name="D", arguments={"message": "D"})
A >> [B, C] >> D # Define execution order
# Create the workflow directly on your Argo Workflows cluster!
w.create()
```
Check out the [Walkthrough](https://hera.readthedocs.io/en/latest/walk-through/hello-world/) to learn how to construct
and submit Argo Workflows with Hera!
## Requirements
Hera requires an Argo Workflows server to be deployed to a Kubernetes cluster. To learn how to deploy Argo to your own
Kubernetes cluster you can follow the [Argo Workflows](https://argoproj.github.io/argo-workflows/quick-start/) guide!
### Authenticating in Hera
Hera assumes that the Argo server sits behind an authentication layer, so workflow submission requests are authenticated
using a Bearer token on the request. Another option for workflow submission without the authentication layer is using
port forwarding to your Argo server deployment and submitting workflows to `localhost:2746`.
There are a few ways to authenticate in Hera - read more in the
[authentication walkthrough](https://hera.readthedocs.io/en/stable/walk-through/authentication/) - for now, with the
`argo` cli tool installed, and the server port-forwarded to `localhost:2746`, this example will get you up and running:
```py
from hera.workflows import Workflow, Container
from hera.shared import global_config
from hera.auth import ArgoCLITokenGenerator
global_config.host = "http://localhost:2746"
global_config.token = ArgoCLITokenGenerator
with Workflow(generate_name="local-test-", entrypoint="c") as w:
Container(name="c", image="docker/whalesay", command=["cowsay", "hello"])
w.create()
```
